If polymerized tung oil isn't lusterous enough you are doing it wrong. I worked at lee valley for a while and I am very familiar with that product. If it's not popping you are either not sealing it, not buffing it (the hand rub in hand rubbed finish), or not applying enough coats. This is a finish that has a learning curve and can be somewhat unforgiving due to a tendency to dry super fast on some conditions, because of this it is recommended to read and follow the instructions.
Also, if you want something to look like it was coated in glass, try nitrocellulose lacquer, in many coats, its self levelling and can really make wood pop, it's the finish often used on custom guitars to achieve a super clear super pop finish.
